WATER-FEEDING DEVICE.

Original application 'filed May 10, 1911, Serial No. 626,171. Dividedand this application filed June 20, 1912. Serial navo r'sas.

To all whom it may concern Be it known that we, JOHN A. WALKUP andCHARLES W. VVALKUP, citizens of the United States, residingin l/Vaco,Texas, have invented certain Improvements in VVater- Feeding Devices,(being a division of application filed May 10,1911, Serial No. 626,171,now Patent No. 1,030,693, dated June 25, 1912,) of which the-followingis a specification.

One object of our invention is. to provide a novel form of container orreservoir which shall include conveniently operative means whereby itshall be possible to adjust the rate of discharge of liquid; thearrangement of parts being such that the device shall be inexpensive tomanufacture, compact in form and convenient to use.

We also desire to provide a novel and simple adjustable barometrlcliquid feeding device whose adjusting means shall be capable of accurateregulatlon to vary the amount of liquid discharged in a given time.

These objects we attain as hereinafter set forth, reference being had tothe accompanying drawings, in which,

Figure 1 is a front elevation of our liquld feeding device, and, Fig. 2is a vertical section of the feeding device taken on the line a-a Fig.1.

In the above drawings, 1 represents a tray or other form of container orbody to which it is desired that liquid shall be gradually fed, and inthis is mounted the barometric liquid feeding container 2, consisting ofa metallic or other vessel having the lower half of one of its sidesbent or extended inwardly as indicated at 3, and cut off so as toterminate a short distance from and substantially parallel with itslower side or bottom in a sealing edge. Adjacent the front edge of thebottom 1, we mount an adjustable set screw 5 whereby the container 2may, within certain limits, be t1lted on its rear edge or corner 6, sothat 1ts front or liquid discharging edge 7 may be raised to a levelimmediately adjacent or, if desired, above a horizontal plane throughthe sealing edge 8 of the inwardly bent side 3.

Under conditions of use the container 2 may be filled with the desiredliquid, for example, water, and after the set screw 5 has beensufficiently extended, said container is placed in the tray 1 in theposition shown in the drawing. The outflow of liquid is then preventedsince the line of the sealing edge Sis below the horizontal planeextendingthrough the liquid discharging edge 7, and the entrance of airto the container is effectually prevented. Thereafter by turning the setscrew 5, the liquid discharging edge 7 may be lowered until finally itis slightly below the horizontal plane of the sealing edge 8, whereupona small quantity of air is permitted to pass below said edge. Acorresponding quantity of liquid in the container 2 is thus permitted toflow out over the edge 7 into the tray or other receptacle and this flowis substantially continuous, the amount discharged depending upon theadjustment of the set screw.

It will be noted that with the arrangement of parts shown, there isalways a body of liquid exposed between the sealing and waterdischarging edges so that if desired, the device may be used as afountain independently of the tray.

Ve claim:

1. The combination of a container having an inwardly extended sideterminating in an edge spaced away from the adjacent bottom portionthereof; said bottom portion having an edge extending to a level abovethat of said edge of the side; with a screw mounted in said bottomportion for adjusting the height of the former edge relatively to thatof the latter edge.

2. A liquid feeding device consisting of a liquid containing vesselhaving a straight discharging edge and also having a rigidly connectedportion terminating in a sealing edge; with means for adjusting theposition of the container to vary the distance of the liquid dischargingedge from a horizontal plane passing through the sealing edge.

3. A barometric liquid feeding device consisting of a reservoir havingan internal edge normally sealed against the admission of air; and ascrew mounted to partially support said reservoir, the same beingadjustable to vary the rate of discharge of liquid therefrom.

4. A liquid feeding device consisting of a container in the form of abox having an in- 5. The combination of a barometric feeding device inthe form of a reservoir havinga water discharging edge and a sealingedge; with means for adjusting said reservoir to simultaneously vary therelative levels of said two edges and thereby vary the rate of dischargeof liquid therefrom.

6. The combination in a liquid feeding.

tially support the reservoir; the side of said reservoir adjacent theliquid discharging edge being extended inwardly and terminating in asealing edge spaced away from said bottom portion.

'In testimony whereof, We have signed our names to this specification inthe presence of two subscribing witnesses JOHN AJWALKUP. CHARLES w.WALKUP.
